Just search "skepticism", "French", or "Spanish" on Area51. Each has at least two identical or nearly-identical proposals (and both Skepticism ones are on the verge of entering the commitment phase). They all have comments referencing their twin, but so far nothing seems to have been done to actually merge them.

Is it better to "pick a winner" and follow it (hoping to divert the split attention), or just go with the flow and follow both? What happens if both start up?
